Reduction of HARQ latency for URLLC 5G services based on network slicing and massive MIMO hybrid beamforming

Ultra-Reliable and Low-Latency Communications (URLLC) is one of the three generic 5G services and probably the most challenging one, with strict quality of service requirements of 99.999% or more reliability and less than 1 milliseconds (ms) radio latency. To achieve latency targets, contributors to...
